Lub xub pwg rail yog dab tsi?
Rail lub xub pwg yog nrum nyob rau hauv lub pob zeb rail ties los kho cov elastic rail clips. Muaj ob hom kev tsheb ciav hlau lub xub pwg nyom muaj, cam khwb cia hauv lub xub pwg nyom thiab lub xub pwg nyom, ob qho tib si yog siv los kho cov elastic rail clips.
Cast-in rail xub pwg
Lub xub pwg nyom casting raws li cov embedded ib feem ntawm railway fastening system yog nias nyob rau hauv qhob pw tsaug zog thiab ua hauj lwm ua ke nrog cov E clip kom fasten lub rail. Cov cam khwb cia hauv lub xub pwg yog tsim los ntawm kev nrum hlau, xws li, GB / T 1348-1988, NF EN 1563 (1997), ISO1038, DIN 1693, JIS G5502 (2001), KS D 4302, GOST 7293 (1985) los yog BS EN 1563 (1997).

Weld-on xub pwg
Weld-on lub xub pwg nyom yog siv nyob rau hauv txoj hauj lwm ntawm txoj kev tsheb ciav hlau qhov twg txoj kev tsheb ciav hlau lub xub pwg yog weld ntawm tiaj steel phaj es tsis yog tus qauv tsheb ciav hlau khi phaj. Weld-on lub xub pwg nyom yog tsim los ntawm kub forging, raws li AREA tus qauv. Cov ntaub ntawv rau weld-on lub xub pwg nyom ntau lawm tuaj yeem qis lossis nruab nrab carbon steel, raws li cov neeg siv khoom xav tau.
Rau cov ntaub ntawv: Cov rail cam khwb cia hlau lub xub pwg nyom tuaj yeem welded rau ntev ntev steel sleeper seem lossis bearers, rau qhov chaw uas fabrication ntawm hloov thiab hla layouts uas ntsug rail geometry yog ua hauj lwm. Lub xub pwg railway lub peev xwm yuav welded nyob rau hauv lub tshwj xeeb txoj hauj lwm raws li dictated los ntawm lub layout tsim, qhov no ua rau nws tshwj xeeb tshaj yog pab tau thiab raug nqi nyob rau hauv cov ntaub ntawv no.
GNEE RAIL, yog ib lub tuam txhab tsim kev tsheb ciav hlau fasteners, uas cov khoom siv npog thaj tsam ntawm kev tsheb ciav hlau, nroog tsheb ciav hlau, mining, thiab lwm yam. Nrog ntau xyoo tshwj xeeb hauv kev tsheb ciav hlau fasteners, GK tau ua haujlwm rau ntau lub khw muag khoom thoob ntiaj teb, suav nrog Tebchaws Meskas, Chile, Argentina, Ecuador. , Brazil, Thaib, Indonesia, Malaysia, Nyab Laj, Spain, Ltalis, Romania, England, Kazakhstan, thiab lwm yam.
Cim npe nrov: cam khwb cia-nyob rau hauv thiab weld-on rail lub xub pwg railway fastening, Tuam Tshoj cam khwb cia-nyob rau hauv thiab weld-on rail lub xub pwg railway fastening manufacturers, lwm tus neeg, Hoobkas
